Researchers Develops a New Material for White TADF Light Emitting Devices

An international joint research group succeeded in developing a novel thermally activated delayed fluorescence (TADF) material which displays emission of light in colors from green to deep-red through Intersystem Crossing from the singlet to the triplet excitons, a world first. The results will contribute to R&D in white TADF light emitting devices for indoor and outdoor use through combination with TADF materials that emit light in shorter wavelengths (deep blue to yellow).

For three decades, white LEDs have depended on rare earth materials such as yttrium aluminum garnet (YAG) layered onto a blue LED chip (Figure 1). Seoul Viosys Co., Ltd. (KOSDAQ: 092190) today announced that it has broken that dependence. It h... READ MORE
